"It wasn't too long ago that I was sitting down to write a review of the ThinkPad X60s which, at the time, was a pretty exciting product. The X60s, and it's slightly heavier counterpart, the X60, are still both very relevant notebooks, but they have since been replaced with newer models. The two new systems, the X61 and the X61s, are very similar to the models that came before them, but take advantage of some of the same technological upgrades that were brought to other new models, like the T61 and R61."
